Pilot Lighting Instructions:
Operating Instructions
Pilot Light:
1.Turn off the gas to the fireplace. If not recently done, remove the glass and let the unit air out
for at least five (5) minutes to clear out any gas. Turn on gas to the heater. Leak test all joints
with soapy water. NEVER USE OPEN FLAME FOR LEAK TESTING.
2.Start the pilot by pressing the gas control knob and turning it to PILOT.
While holding the gas control knob in, press the piezo ignitor several
times until the pilot light starts. Hold the gas control knob in for 30
seconds. Check that the pilot has fully engulfed the thermocouple
assembly (see Figure 3).

3.Start the main burner by turning the gas control knob to ON and then
turn the rocker switch to ON. Check that all burner ports have flame.
4.Leak test all gas joints again.
Figure 3. Pilot Flame
Air Shutter:
The air shutter is controlled with the primary air adjustment rod located behind the gas valve shown in
Figure 4.
The air shutter allows the amount of air coming into the fireplace to be adjusted in order to accommodate
different climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot
flame is burning normally and none of the burner ports are plugged. Let the fireplace burn for roughly
fifteen (15) minutes and then examine the flames, compare the flames to Figure 61.
The ideal flame will be blue at the base and light
orange above. The flames should be of medium
height. If the flames look like this, no venturi
adjustment is needed. If the flames are fairly
short and mostly blue, the fireplace is getting
too much air. Therefore, the air shutter should
be closed slightly until the correct flames are
achieved. Flames that are very orange, with tall,
dark, stringy tips, are not getting enough air.
Open the venturi until the flames clean up. If the
venturi is opened, or closed all the way, and the
correct flames cannot be attained, turn off the
gas and contact the dealer.

Operating Instructions
For Your Safety, Read Safety Precautions And
Lighting Instructions Before Operating
Remote controls (Optional):
This fireplace can use an optional remote control or an optional cordless wall thermostat. If either of
these are to be used to control the fireplace for the majority of the time, leave the ON/OFF switch (on the
control panel) in the remote/thermostat position. Consult the instructions included with the remote/wall
thermostat for operation guidelines.
Blower Speed (Optional):
The blower will come on only when the fireplace is up to temperature (approximately 20 minutes). The
speed of the fan can be changed by turning the fan control knob. To turn the blower off, turn the knob
COUNTER CLOCKWISE until it “clicks” off.
It is advisable not to operate the blower below 1/3 speed as it puts a strain on the windings of the blower
and running the blower at lower speeds could also cause premature fan failure.

Maintenance And Service
Routine Maintenance:
At least once a year, run through the following procedures to ensure the system is clean and working
properly. Check the burner to see if all the ports are clear and clean. Check the pilot to make sure it is not
blocked by anything. The pilot flame should be blue with little or no yellow on the tips.
Warning: Clearances must be sufficient to allow access for maintenance and service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specifically approved with this appliance may result in property damage or personal injury.
The venting system must be periodically examined; it is recommended the examination is done by a
qualified agency.
Cleaning The Glass:
When the fireplace has cooled, remove the face of the fireplace along with the glass. See Maintenance
And Service - Glass Door Removal. Check the gasket material on the back of the glass, making sure that it
is attached and intact.
During a cold start up, condensation will sometimes form on the glass. This is a normal condition with all
fireplaces. However, this condensation can allow dust and lint to cling to the glass surface. Initial paint
curing of the appliance can leave a slight film behind the glass, a temporary problem. The glass will need
cleaning about two weeks after installation. Use a mild glass cleaner and a soft cloth; abrasive
cleaners will damage the glass and plated surfaces. Depending on the amount of use, the glass
should require cleaning no more than two or three times a season. Do not clean the glass when it is
hot.
Cleaning The Firebox:
Remove the logs carefully, as they are very fragile. Gently remove all the embers and rock wool and
place on a paper towel. Vacuum the bottom of the firebox thoroughly. Carefully clean any dust off the
logs and remove any lint from the burner and pilot. At this time, inspect the burner pan for cracking or
severe warping. If a problem is suspected, contact the dealer. Check the logs for deterioration or large
amounts of soot; a small amount on the bottom side of the logs is normal. Replace the logs and embers
as in the Log Set and Ember Installation section. If new/more embers and rock wool are required, contact
your nearest ENVIRO dealer.
Change Battery in Ignition Module:
If the unit does not spark when lighting, the battery in the
electronic ignition could need replacing.
Located on the left hand rear corner of the unit is a small
rectangular hole. Located here is the electronic ignition module
(see Figure 5). Remove the battery cover, located on the left side
of the module, and replace the AA battery.
Reinstall the battery cover and check for spark by depressing the
pilot knob located on the control panel.

particular requirements. It is important to note when passing through a wall, the maximum allowable
wall thickness is 10 inches (25.4 cm), 1½ inches (3.8 cm) clearance to combustibles must be maintained.
Select the amount of vertical rise desired for “vertical-to-horizontal” type installations. To determine
the length of vent pipe required for vertical installations, measure the distance from the appliance flue
outlet to the ceiling, the ceiling thickness, the vertical rise through the attic or second story, and allow
for sufficient vent height above the roof line. For two story applications, a fire stop is required at each
floor level. If an offset is needed in the attic, additional pipe and elbows will be required. To connect the
venting system to the appliance flue outlet, a twist-lock adapter is built into the appliance at the factory.

components are missing or damaged.
INSTALLATION INSTRUCTIONS:
1. Plan your installation and clearances to combustibles. Decide on a location for the unit that will meet
the clearances noted in the venting section, and any or all local code requirements.
2. Set the appliance in the desired location. Determine if any wall studs, electrical wiring, or plumbing
pipes are in the way of the venting system as it passes through the exterior wall. The fireplace location
should be adjusted if obstructions are found in the wall.
3. Project a line from the center point of the flue outlet upward and outward to the desired flue outlet
location on the exterior wall. Using this center point, scribe a 10” (25.4 cm) hole or square on the wall.
Cut the hole from the interior through the exterior wall surfaces.
4. Frame the hole as shown in Figure 26.
5. Trim the wall thimble to match the wall thickness as necessary. Install the wall thimble and secure
it to the inner wall frame using four (4) 1½” wood screws. If a wall is
greater than 8” (203mm) in depth, the clearance above the flex must be
4⅜” (111mm)
6. Apply a bead of Mill-Pac Black sealant to the new Ø4” (10 cm) by 5” (12.5
cm) provided flue collar adaptor. Press the flue collar into the flue outlet of
the fireplace so that the Mill-Pac seals the flue collar to the flue outlet.
7. Stretch both the Ø4” (10 cm) flex vent and the Ø6⅝” (16.25 cm) flex intake
liner to the length needed to ensure the flex can be easily connected to the
vent terminal.

Vent Configurations and Restrictor Settings:
Figures 23 & 24 show the range of venting options, they show possible vent configurations if the unit is
top vented (see Figure 23) or rear vented (see Figure 24), for vertical and horizontal terminations, any
layout that remains within the shaded area is acceptable. Having the fewest number of elbows is ideal,
as they tend to disrupt air movement. Using 45˚ elbows is preferable to using 90˚ elbows. Also, a shorter
vent system will perform better than a longer one.
The ENVIRO WESTPORT has been designed with a built in restrictor
plate. The restrictor is designed to enhance flame appearance when
installing this unit with vertical chimneys as well as installations with
longer horizontal vent applications. It does this by controlling the
amount of air moving through the vent pipe.

Initial Installation
QUALIFIED INSTALLERS ONLY
Horizontal Installation:
1. Set the appliance in the desired location. Check to determine if wall studs or roof rafters are in the
way when the venting system is attached. If this is the case, you may want to adjust the location of
the appliance.
2. Direct vent pipe and fittings are designed with special twist-lock
connections. Assemble the desired combination of black pipe and
elbows to the appliance adapter with pipe seams oriented towards
the wall or floor, as much out of view as possible.
Place a bead of Mil-Pac on the outer edge of the inner exhaust pipe
(non-flared end). Place a bead of high temperature silicone on the
male edge of the outer pipe. Push the pipe sections completely
together, then twist-lock one section clockwise approximately ¼
turn, until the two sections are fully locked. The female locking
lugs will not be visible from the outside, on black pipe. They may
be located by examining the inside of the female ends as shown in
Figure 25.
Notes:
(a) Twist-lock procedure: four (4) indentations, located on the female
end of the pipes and fittings, are designed to slide straight onto the
male ends of adjacent pipes and fittings, by orienting the four pipe
indentations so they match and slide into the four entry slots on the
male end.
(b) Horizontal runs of vent pipe must be supported every 36” (915mm).
Wall straps are available for this purpose, also when running horizontal
pipe minimum clearances to combustibles must be maintained;
2” (51mm) at top, 1½” (38mm) at sides, 1½” (38mm) at
bottom.

3. With the pipe attached to the stove in the correct location, mark the
wall for a 10” (25.4cm) x 10” (25.4 cm) square hole (refer to Figure
26). The center of the square hole should match the center line of
the horizontal pipe. Cut and frame the 10” (25.4cm) x 10” (25.4cm) Figure 26: Wall Framing Hole for

wall, run a bead of non-hardening mastic around the edges, so as to make a seal between the
termination and the wall. The arrow on the vent termination should be pointing up, insure that the
proper clearances to combustible materials are maintained.
5. Before connecting the horizontal run of the vent pipe to the vent termination, slide the black decorative
wall thimble cover over the vent pipe.
6. Slide the appliance and vent assembly towards the wall, carefully inserting the vent pipe into the
cap assembly. It is important that the vent pipe extend into the vent cap a sufficient distance with a
minimum of 1¼” (3.2cm) overlap. Secure the connection between the vent cap pipe and the vent cap
by attaching the two sheet metal straps extending from the vent cap assembly into the outer wall of
the vent pipe. Use the two sheet metal screws provided to connect the straps to the vent pipe. Bend
any remaining portion of the sheet metal straps back towards the vent cap, so the decorative wall
thimble will conceal it (see left image in Figure 27).
7. Slide the decorative wall thimble up to the wall surface and attach with the screws provided. Apply
decorative brass or chrome trim if desired (see right image in Figure 27).
NOTES:
(a) The four (4) wood screws provided should be replaced with the appropriate fasteners for stucco,
brick, concrete, or other types of siding.
(b) For buildings with vinyl siding, a vinyl siding standoff, should be installed between the vent cap and
the exterior wall (see Figure 28). Attach the vinyl siding standoff to the horizontal termination. The vinyl
siding standoff prevents excessive heat from possibly melting the vinyl siding material. Note that the
horizontal vent termination bolts onto the flat portion of the vinyl siding standoff (shaded area in Figure
28), so that an air space will exist between the wall and the vent termination.
(c) The horizontal run of vent pipe must be level and should have a ¼ inch rise for every one
foot of run towards the termination. Never allow the vent to run downward. This could cause high
temperature and may present the possibility of a fire.
(d) The location of the horizontal vent termination on the exterior wall must not be easily blocked or
obstructed. Refer to Initial Installation - Vent Configurations and Restrictor Settings.
(e) When installing a vent pipe in a chase the minimum clearance to combustibles is 2” (51 mm).
(f) Maintain manufacturer’s clearances to combustibles with venting.

QUALIFIED INSTALLERS ONLY
Vertical Installation:
1. Check the instructions for required clearances (air spaces) to combustibles when passing through
ceilings, walls, roofs, enclosures, attic rafters, or other nearby combustible surfaces. Do not pack air
spaces with insulation.
2. Set the gas appliance in the desired location. Drop a plumb bob down from the ceiling to the position
of the appliance flue exit, and mark the location where the vent will penetrate the ceiling. Drill a small
hole at this point. Next, drop a plumb bob from the roof to the hole previously drilled in the ceiling,
mark the spot where the vent will penetrate the roof. Determine if ceiling joists, roof rafters, or other
framing will obstruct the venting system. You may wish to relocate the appliance, or to offset, to avoid
cutting load bearing members.
3. To install the Round Support Box/Wall Thimble in
a flat ceiling, cut a 10” square hole in the ceiling,
centered in the hole drilled in Step 2. Frame the
hole as shown in Figure 30.
Ceiling Joist
Framing
4. Assemble the desired lengths of black pipe and
elbows necessary to reach from the appliance
adapter up through the Round Support Box.
Insure that all pipe and elbow connections are in
their fully twist-locked position.
5. Cut hole in the roof centered on the small
hole placed in the roof from Step 2. The hole
should be of sufficient size to meet minimum
requirements for Clearance to Combustibles, as
specified. Continue to assemble lengths of pipe
and elbows necessary to reach from the ceiling
support box up through the roof line. Galvanized
pipe and elbows may be utilized in the attic, as
well as above the roof line. The
galvanized finish is desirable
above the roof line, due to the
higher corrosion resistance.
Elbow Strap
6. Once the pipe sections have
been joined, and run up through
the hole in the roof, slip an elbow
strap over the exposed sections,
bend
the
support
straps
outwards, and push the elbow
strap down to the roof level, as
shown in Figure 31. Tighten the
clamp around the pipe section.
Use a level to make sure the
pipe is truly vertical. With
roofing nails, secure the support
straps to the roof. Seal the nails

the support straps that extend out beyond the edge of the flashing.
7. Slip the flashing over the pipe section protruding through the roof. Secure the base of the flashing to
the roof with roofing nails. Use a non-hardening sealant between the uphill edge of the flashing and
the roof. Insure the roofing material overlaps the top edge of the flashing as shown in Figure 30. Verify
that you have at least the minimum clearance to combustibles at the roof line.
8. Continue to add pipe sections until the height of the vent cap meets the minimum code requirements.
Refer to Figure 32 and Table 6. Note that for steep roof pitches, the vent height must be increased. In
high wind conditions, nearby trees, adjoining roof lines, steep pitched roofs, and other similar factors
can result in poor draft, or down drafting. In these cases, increasing the vent height may solve the
problem.
9. Slip the storm collar over the pipe, and push it down to the top of the roof flashing as shown in Figure
31. Use the non-hardening sealant around the joint between the pipe and the storm collar.
10. Twist-lock the vent cap.

(a)If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe
every 3 feet (91 cm), to avoid excessive stress on the elbows, and possible separation. Wall straps
are available for this purpose (see Figure 33).
(b)When ever possible, use 45° degree elbows instead of 90° degree elbows. The 45° degree elbow
offers less restriction to the flow of flue gases and intake air.
(c) For multi story installations. A ceiling firestop is required at the second floor, and any subsequent
floors (see Figure 34). The opening should be framed to 10” (25.4 cm) x 10” (25.4 cm) inside
dimensions, in the same manner as shown in Figure 30.
(d) Any occupied areas above the first floor, including closets and storage spaces, which the vertical vent
passes through, must be enclosed. The enclosure may be framed and sheet rocked with standard
building materials. However consult the appliance manufactures installation instructions for the
minimum allowable clearance between the outside of the vent pipe, and the combustible surfaces of
the enclosure. Do not fill any required air spaces with insulation.

GENERAL VENTING INFORMATION:
Canadian Installations
The venting system must be installed in accordance with the current CSA B149 installation code and/or
local codes having jurisdiction.
U.S.A. Installations
The venting system must be installed in accordance with the current National Fuel Gas Code, ANSI
Z223.1, and/or local codes having jurisdiction.
29
Initial Installation
The minimum clearance to combustibles is 6” (150 mm) when using single wall venting and 1” (25 mm)
when using “B-vent” venting.
We strongly recommend installing an approved chimney liner in an existing brick chimney. This will
maximize the potential draft of the chimney and lessen the effects of slow chimney start-up.
VENTING OF A FIREPLACE FITTED WITH THE DRAFTHOOD ADAPTOR:
Note: Please refer to the chimney manufacturer’s installation instructions prior to commencing the
installation.
This unit may be vented to an existing masonry
chimney, or where no masonry chimney is available,
an approved “B-vent” chimney, or any other approved
constructed chimney/vent system (see Figure 46 &
47).
6" (15cm)
optional
decorative
cover
In either case, the fireplace may be connected to
the chimney/vent using a 4” (10 cm) single wall vent
connector.
4" (10cm)
vent
When an existing masonry chimney is utilized for
the venting, we recommend the vent connector be
connected to an approved 4” (10 cm) diameter flue
liner running the full height of the chimney. In many
jurisdictions this flue liner may be mandatory.
If 4” (10 cm) single wall vent is used, a minimum of
6” (15 cm) must be maintained between the vent
connector and any combustibles.
Figure 46: Unit top venting styles.
If 4” (10 cm) “B-vent” is used a minimum of 1” (25
mm) must be maintained between the vent connector and any combustibles.
CAUTION: A minimum vent height of 12’ (3.6 m) from the floor is required to effectively vent this
fireplace.
SPILLAGE TEST:
A spillage test must be performed prior
to leaving the installed fireplace with the
customer. Perform this test in the following
manner:
Check vent draft
at the top row of
opening.
1. Close all windows and doors in the room.
2. Start all exhaust fans in the house and the
furnace blower.
3. Light the fireplace and set to maximum
flame adjustment.
Figure 47: Unit rear
venting style.
30
4. After a minimum of 10 minutes operation,
test the chimney draft with a smoke match
at the top row of the pattern to confirm
that there is adequate draft or ‘pull’ at the
openings around the body of the Drafthood
Adaptor, as shown in Figure 48.
Figure 48: Draft test place.
Initial Installation
AUTOMATIC SAFETY SHUT DOWN:
If the spill switch is activated and shuts off the main burner the following procedure should be
followed.
• Is the pilot flame still on? If not, the reason for the fireplace shut down is not the spill switch.
• Turn off the pilot flame and turn off all controls. Let fireplace to cool down.
• Check for blockages or restrictions in the flue and venting components.
• Restart the fireplace and check for vent draft as described earlier.
• Operate the fireplace in a normal manner.
• If the main burner shuts down again after a period of operation, turn off the fireplace and contact your
service technician.
SPILL SWITCH REPLACEMENT:
Use the following instructions to replace the
Safety Spill Switch.
1. Turn the unit off and allow it to cool.
2. Disconnect the spill switch wires from the
valve and on/off/remote rocker switch wire
(see Figure 45).
3. Remove the four mounting screws holding
the spill switch bracket and remove the
bracket (see Figure 49).
4. Remove and replace the spill switch with a
50-885 Spill Switch Assembly using a T-20
torx type driver.
5. Follow the reverse of the previous steps.
Figure 49: Spill switch installation.
OPTIONAL FINISHING:
In installations where the flue connector is running from the drafthood into a non-combustible chimney
the following optional finishing technique can be used.
CAUTION: Installations where the flue connector or venting connects to, or passes through,
combustible walls or ceilings, the inner vent components must be ‘B-vent’. It is not allowable
in these applications to use single wall inner vent components.
For decorative purposes a 6” (15 cm) single wall black stove pipe may be installed over the 4” (10 cm)
single wall or ‘B-Vent’.
Note: The use of these components is for aesthetic purposes only and does not effect the
fact that the fireplace, when fitted with the Drafthood Adaptor, is a Natural Vent appliance
and therefore draws air in through the Drafthood Adaptor intake ports.

Warranty
Sherwood Industries Ltd. is the manufacturer of the Enviro line of heating products. At Sherwood Industries, our
commitment to the highest level of quality and customer service is the most important thing we do. Each Enviro stove
is built on a tradition of using only the finest materials and is backed by our Exclusive Lifetime Limited Warranty to
the original purchaser. With Enviro, you’re not just buying a fireplace or stove, you’re buying a company with years of
unequalled performance and quality.
Limited Lifetime Warranty:
Under this warranty, Sherwood Industries Ltd. covers the fireplace or stove body and accessories against defects in
materials and workmanship, for part repair or replacement for the first seven (7) years and limited labour for the first
two (2) years to the original purchaser. This Warranty covers: Firebox, Heat Exchanger, Steel Firebox Panels, Ceramic
Logs & Panels, Burner, Ceramic Glass, Pedestals, Panels and Legs. Please see the exclusions and limitation section
below as certain restrictions and exclusions apply to this warranty.
Limited Two (2) Year Warranty:
Under this warranty, Sherwood Industries Ltd. covers: Gas Assembly, Blower, Blower control, Temperature Sensors and
Wire Harness against defects in materials and workmanship, for part repair or replacement for the first two (2) years
and limited labour for the first two (2) years to the original purchaser. Please see the exclusions and limitation section
below as certain restrictions and exclusions apply to this warranty.
Limited One (1) Year Warranty:
Under this warranty, Sherwood Industries Ltd. covers all exterior surface finishes against defects in materials and
workmanship, for part repair or replacement and limited labour for the first (1) year to the original purchaser. Please
see the exclusions and limitations section below as certain restrictions and exclusions apply to this warranty.
Here is how our Warranty works
If you have any concerns with your Enviro product, please contact the dealer where you purchased the fireplace or
stove. Your dealer shall make all claims under this warranty in writing.
To the Dealer
When filling out a warranty claim, please complete the following information on an official warranty claim form:
Customer information: Name, address and telephone number of purchaser and date of purchase.
Dealer information: Date of installation, name of installer and dealer, serial number of the appliance, nature of
complaint, defects or malfunction, description and part numbers of any parts replaced.
To the Distributor
Sign and verify that work and information are correct.
Exclusions and Limitations:
1. This Warranty does not cover tarnish, discoloration or wear on the plating or paint.
2. This Warranty excludes wear and tear or breakage caused by cleaning, moving or service on log set and panels.
3. A qualified installer must install this stove or fireplace. This Limited Warranty covers defects in materials and workmanship
only if the product has been installed in accordance with local building and fire codes; in their absence, refer to the owner’s
manual. If the product is damaged or broken as a result of any alteration, willful abuse, mishandling, accident, neglect, or
misuse of the product, the Limited Warranty does not apply.
4. The stove must be operated and maintained at all times in accordance with the instructions in the Owner’s Manual. If the
unit shows signs of neglect or misuse, it is not covered under the terms of this Warranty policy. Performance problems due
to operator error will not be covered by the Limited Warranty policy.
5. As this is a heating appliance, some changes in colour of surface finishes may occur. This is not a flaw and as such is not
covered under this warranty.
6. Some minor expansion, contraction, or movement of certain parts and resulting noise, is normal and not a defect and,
therefore, is not covered under this Limited Warranty.
7. Misuse includes over-firing. Over-firing this appliance can cause serious damage and will nullify the Limited Warranty.
8. The Limited Warranty will cover glass thermal breakage only and will not cover misuse of the stove glass, including but not
limited to glass that is struck, has surface contaminates or has had harsh or abrasive cleaners used on it.
9. This warranty does not cover products made or provided by other manufacturers and used in conjunction with the
operation of this stove without prior authorization from Sherwood Industries Ltd. The use of such products may nullify the
Limited Warranty on this stove. If unsure as to the extent of this Limited Warranty, contact your authorized Enviro dealer
before installation.
10. Sherwood Industries Ltd. will not be responsible for inadequate performance caused by environmental conditions.
11. The Limited Warranty does not cover installation and operational related problems such as use of downdrafts or spillage
caused by environmental conditions. Environmental conditions include but are not limited to nearby trees, buildings, roof
tops, wind, hills, mountains, inadequate venting or ventilation, excessive offsets, negative air pressures or other influences
46
Warranty
caused by mechanical systems such as furnaces, fans, clothes dryers etc.
12. The Limited Warranty is void if:
a) The stove has been operated in atmospheres contaminated by chlorine, fluorine or other damaging chemicals.
b) The stove is subject to submersion in water or prolonged periods of dampness or condensation.
c) Any damage to the unit, combustion chamber or other components due to water, or weather damage which is the result
of, but not limited to, improper chimney/venting installation.
c) Salt air in coastal areas or high humidity can be corrosive to the finish; these environments can cause rusting. Damage
caused by salt air or high humidity is not covered by the Limited Warranty.
13. Exclusions to the Limited Warranty include: injury, loss of use, damage, failure to function due to accident, negligence,
misuse, improper installation, alteration or adjustment of the manufacturer’s settings of components, lack of proper and
regular maintenance, alteration, or act of God.
14. The Limited Warranty does not cover damage caused to the fireplace or stove while in transit. If this occurs, do not
operate the stove and contact your courier and/or dealer.
15. Limited Warranty does not extend to or include firebox paint, door or glass gaskets with damage caused by normal wear
and tear, or exterior paint discoloration or chipping, worn gaskets, etc.
16. The Limited Warranty does not include damage to the unit caused by abuse, improper installation, or modification of the
unit.
17. Damage to plated surfaces caused by fingerprints, scratches, melted items, or other external scores and residues left on
the plated surfaces from the use of abrasive cleaners or polishes is not covered in this warranty.
18. The Limited Warranty does not cover tarnish, discoloration or wear on the plated surfaces.
19. The paint on the Metal Brick Liner may peel. This is due to the extreme conditions applied to the paint during normal
usage. It is not a flaw and is not covered under warranty.
20. Sherwood Industries Ltd. is free of liability for any damages caused by the fireplace or stove, as well as inconvenience
expenses and materials. The Limited Warranty does not cover incidental or consequential damages.
21. The Limited Warranty does not cover any loss or damage incurred by the use or removal of any component or apparatus
to or from the Enviro fireplace or stove without the express written permission of Sherwood Industries Ltd. and bearing a
Sherwood Industries Ltd. label of approval.
22. Any statement or representation of Enviro products and their performance contained in Enviro advertising, packaging
literature, or printed material is not part of the Limited Warranty.
23. The Limited Warranty is automatically voided if the fireplace or stove’s serial number has been removed or altered in any
way. If the stove is used for commercial purposes, it is excluded from the Limited Warranty.
24. No dealer, distributor, or similar person has the authority to represent or warrant Enviro products beyond the terms
contained within the Limited Warranty. Sherwood Industries Ltd. assumes no liability for such warranties or representations.
25. Sherwood Industries Ltd. will not cover the cost of the removal or re-installation of the stove, hearth, facing, mantels,
venting or other components.
26. Labour to replace or repair items under this Limited Warranty will be covered per our warranty service fee reimbursement
schedule. Labour rates are set per component and as such total labour costs may not be covered.
27. Sherwood Industries Ltd. is not liable for freight or labour on any stove replaced in-field and is not liable for travel costs
for service work. In the event of in-home repair work, the customer will pay any in-home travel fees or service charges
required by the Authorized Dealer.
28. At no time will Sherwood Industries Ltd. be liable for any consequential damages which exceed the purchase price of the
unit. Sherwood Industries Ltd. has no obligation to enhance or modify any stove once manufactured (example: as a stove
evolves, field modifications or upgrades will not be performed).
29. This Limited Warranty is applicable only to the original purchaser and it is non-transferable.
30. This warranty only covers Enviro products that are purchased through an authorized Enviro dealer.
31. If for any reason any section of the Limited Warranty is declared invalid, the balance of the warranty remains in effect and
all other clauses shall remain in effect.
32. The Limited Warranty is the only warranty supplied by Sherwood Industries Ltd., the manufacturer of the stove. All other
warranties, whether express or implied, are hereby expressly disclaimed and purchaser’s recourse is expressly limited to
the Limited Warranty.
33. Sherwood Industries Ltd. and its employees or representatives will not assume any damages, either directly or indirectly,
caused by improper usage, operation, installation, servicing or maintenance of this stove.
34. Sherwood Industries Ltd. reserves the right to make changes without notice. Please complete and mail the warranty
registration card and have the installer fill in the installation data sheet in the back of the manual for warranty and future
reference.
35. Sherwood Industries Ltd. is responsible for stocking parts for a maximum of seven (7) years after discontinuing the
manufacture or incorporation of the item into its products. An exception to this would be if an OEM supplier is not able
to supply a part.
